HORSE'SHOE.

SPECIFICATION forming part of Letters Patent No. 592,998, dated November2, 1897. Application n t-r April 13, 1896. Serial No. 587,361. onmodel.)

To all whom it may concern.-

Be it known that 1, JOHN A. ROTH, of Hannibal, in the county of Monroeand State of Ohio, have invented an Improved Horseshoe,

of which the following is a specification.

This invention relates generally to horseshoes, and particularly to theimproved construction of the heel and toe calks.

The object of this invention is to provide a calk which shall heself-sharpening, so that as the calk is worn down it will always have asharp edge to prevent slipping.

With these objects in view the invention consists, essentially, in acalk form ed of a thin web or outer portion and a series of ribs orthickened portions upon the interior.

The invention consists also in certain details of construction andnovelties of combination, all of which will be fully explained, and thenspecifically pointed out in the claim.

In the drawings hereto annexed, Figure 1 shows the invention in use.Fig. 2 is a detailed view of the shoe. Fig. 3 is a sectional view. Fig.4. is a further section across the calk.

Referring to the drawings, A indicates an ordinary horseshoe, B thetoe-calk, and O the heel-calks. The heel and toe calks are similar inconstruction, except that thetoe-calk is wider. These calks are attachedto the shoe in any well-known manner or they may be formed integraltherewith.

The construction of the calks in detail consists of the outer or webportion D and the series of ribs or thick portions E upon the interior.The web is comparatively thin and will of course wear down first, andthe ribs will thus be left as a series of points to catch a firm hold,thereby preventing the horse from slipping. When the ribs are worn downor smooth, then the web wears again, and so on, thus leaving the pointsof the ribs exposed, so that, in fact, I have a self-sharpening calk.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

As a new article of manufacture, a horseshoe having its ends separatedat the heel, and provided at the toe with a segmental calk and at eachheel end with a calk extending transversely of said end and diagonallywith relation to the toe-calk, said toe and heel calks each comprising acomparatively thin vertical web provided on its inner face with a seriesof vertical ribs broad at the base and tapering gradually therefrom to apoint in line with the lower edge of the web, said web and ribs beingformed integrally with the shoe in the process of manufacturingthe'latter, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOHN A. ROTH.
